• What is 74ACT563SCX?

  74ACT563SCX is a kind of latch circuit.It is a dual digital registers,particularly designed to drive TTL logic.It consists of two serially interconnected clocked D-type flip-flops.This part is used for data or address transfer over short distance and is mainly made to interface input/output with static CMOS gates or AVT logic.It has 3-State outputs for bus-organized systems.

• Application of 74ACT563SCX

  It typically used within data transfer latches or in bit-oriented systems, 74ACT563SCX is used in industry such as small computers, programmable controllers, medical apparatus, communication systems, and instrumentation.

  It’s widely used for high-speed data bus switch buffers, backplane buffers, data storage system, low frequency in-circuit emulators, wide-range active switches etc.It can also be used in audio sampling and engineering diagram and other digital system processing.

• Working Principle Of 74ACT563SCX

  The 74ACT563SCX has two 3-state flip flops, one of which is clocked by a positive transition of the clock (low-to-high transition).It has two active-low reset pins and one set/reset pin. When both the reset pins (1 and 2) are pulled low, then it will reset the flip-flop and the Q output will follow the D input when the clock is low. When the input signals are ones,it will enable the Q-bar output to follow the D-bar input upon the clock transition from low to high.

  TheSet/Resetpin basically overrides both thedata inputandclock inputs.When the S/R pin is brought high both reset pins are ignored by the flip-flops and the Q output follows the S/R pin. Thus when theSet/Resetpin is driven high, the Q output will be high and when the S/R pin is driven low, the Q output will be low.
